GUIDE FOR THREAD; YARN, 8&0

Specification of Letters Patent.

PatenteaMay28,19O7.

Application filed December 3,1906. Serial No. 346.129.

York, county and State of New York, have 5 invented certain new and useful Im )rovements in Guides for Thread, Yarn, c., of which the following is a specification.

In some machines in which thread guides are employed it has been found practically to impossible by the use of guides of ordinary construction to retain the thread in the eye of the guide, inasmuch as in such machines the thread is subjected to vibrations of different characters, which, it has been found, result in gradually working the thread laterally out of the guide eyes or channels, necessitating the stopping of the machines in some cases as the result of breaking or abrading the thread;

To avoid theseobjections I make use of a guide having channels, notches .and fingers arranged in'a peculiar manner hereinafter fully set forth and illustrated in the accompanying drawing which shows in part section a thread. guide embodying my improven'ients.

The guide is'preferably made of porcelain or other vitreous material, or it may be made of metal, coated if desired with enamel, and it consists substantially of the head A and the stem B, the latter having a socket 10 or otherwise being formed for connection to a suitable support. In the head is formed a channel 4, which at one side communicates with the inlet slot 1, which is at an angle to the line of the channel 4, and the upper end of the channel 4 is curved laterally and communicates with a slot 5, at one side and between the ends of the said slot, thereby form-- ing two notches 6, 7, upon opposite sides of the point where the channel 4 communicates with theslot.

The formation of the channel 4 in the head leaves at one side'of the same, and on opposite sides of the slot 1, two fingers 2, '3, and the finger 2 is thickened and the finger 3 is reduced in thickness so that the wide face a: at the end. of iiugerZ extends inward beyond the side of the finger 3. As a result of this construction, it is practically impossible for the thread, whatever may be the character of vibrations imparted thereto, to find its way from the channels or slots of the guide. After the thread passes'through the inlet slot 1 'and through the channel 4 into the slot 5, any

lateral vibrations which would tend to throw it back into the channel 4 would have no tendency to cause it to pass out of the inlet slot 1, as the curved face 9 of the channel would tend to deflect it back into the slot 5, and if it'should slip down below the finger 3, any movementcarrying it toward the finger 2 would cause it to meet the wide face :13 thereof and deflect it back into the'upper part of the channel 4. In most instances, however, the arrangement of the slot 5, extending in both directions beyond the inlet or mouth of the channel 4, will prevent the thread from passing back into the said chan nel, any vibration of the thread naturally carrying it either into the notch 7 or into the notch 6 or against the curved face of the channel 4-, which naturally causes it to slide back into the slot 5. I

What I claim is:

1. A thread guide provided with a head A and a stem B, the head having an inclined inlet slot and a curved channel with which'the slot comuninicates at one side, and a slot ermnnunicating atone side with they upper end of said channel and extending in both directions beyond this point of connnunication with the channel, for the purpose set forth.

2. A thread guide provided with. a stem B and ahead A, the latter having an inlet slot and a channel with which said slot com1nunicates, fingers on opposite sides of said slot,- ,one of said fingers being thicker than the other and. having an inclinedterminal 'l'ace extending inward. beyond the side of said other finger, for thcpurpose described.

3. A thread guide provided with a stem B and a head A, the latter having an inlet slot and a channel with which'said slot communi- 4; A thread guide cbhsisping of 1 stiam and I 3 Intstim ny Wheredf sigl lat ljiiff v ahead, the latter havinga. channel provided in pi'esence of two Witnesses; Wlt-h a ulrved u pen end commumcatlng With a slot exten ing in bofih directions be- JOHN MITCHELL 5 yond the point ofponi'munic'ation', and an in y W itnessegi let slot communicating with said channe? be- JOSEPH MOGRAW,
